Description

Holmium Chloride is a high-purity inorganic salt of the rare earth element holmium, primarily supplied as the hexahydrate form. This compound is valued for its unique optical and magnetic properties, making it a critical precursor in advanced material synthesis. It is essential for researchers and manufacturers in the fields of specialty glass, phosphors, and catalysis who require consistent, high-quality rare earth materials for their processes.

Application

• Specialty Glass & Optical Filters: Used as a dopant to produce specific yellow and red colorations and to create sharp band-pass filters for scientific instruments.
• Phosphor Manufacturing: Serves as a key raw material in the production of phosphors for lighting, display technologies, and X-ray intensifying screens.
• Catalysis Research: Acts as a catalyst or catalyst precursor in organic synthesis and polymerization reactions.
• Laser Crystal Growth: Employed as a starting material for the synthesis of holmium-doped YAG (Yttrium Aluminum Garnet) and other laser host crystals.
• Magnetic Research Materials: Used in the preparation of novel magnetic materials and for studying magnetic properties due to holmium's high magnetic moment.
• Chemical Vapor Deposition (CVD): Functions as a precursor for depositing holmium-containing thin films in semiconductor and coating applications.

Quality Control

Our Holmium Chloride is produced under a stringent quality management system. Each batch undergoes comprehensive analysis to ensure it meets high-purity standards, with trace metal impurities controlled to ppm levels. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming specifications for assay, identity, and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption and potential caking. Keep away from incompatible materials.
